Abstract: A checklist of the known psyllids of Belarus is given: 12 species (one of them doubtful) have been previously
reported and 43 species are added here, bringing the number of confirmed species to 54. The psylloid fauna of the coun-
try remains poorly known. Based on information from surrounding countries, another 73 species can be expected. An
illustrated identification key is provided for the 127 species whose occurence in Belarus has been confirmed or is likely.
Keywords: Psyllids - Sternorrhyncha - host-plants - faunistics - identification key - Europe - Palaearctic Region.
